Graphic abstract Greenhouse gas (GHG) emissions leading to anthropogenic global warming continue to be a major issue for societies worldwide. A major opportunity to reduce emissions is to improve building construction, and in particular the effectiveness of building envelope, which leads to a decrease in operational energy consumption. Improving the performance of a building's thermal envelope can substantially reduce energy consumption from heating, ventilation, and air conditioning while maintaining occupant comfort. In previous work, a computational model of a biomimetic building façade design was found to be effective in temperate climates in an office context. Through a case study example based on animal fur and blood perfusion, this paper tests the hypothesis that biomimetic building facades have a broader application in different building typologies across a range of climate zones. Using bioinspiration for innovation opens new ideas and pathways for technological development that traditional engineering design does not provide. This study exemplifies the process in a building façade, integrating a new form of insulation, heating and cooling. Methods of mathematical modelling and digital simulation methods were used to test the energy reduction potential of the biomimetic façade was tested in a set of operational applications (office, school, and aged care) and across different climate zones (tropical, desert, temperate, and cool continental). Results indicated that the biomimetic façade has potential to reduce energy consumption for all building applications, with the greatest benefit shown in residential aged care (67.1% reduction). Similarly, the biomimetic building façade showed potential to reduce operational services energy consumption in all climate zones, with the greatest energy reductions achieved in the tropical (55.4% reduction) and humid continental climates (55.1% reduction). Through these results the hypothesis was confirmed suggesting that facades engineered to mimic biological functions and processes can improve substantially decrease building operational energy consumption and can be applied in different building classifications and different climate zones. These results would significantly decrease operational greenhouse gas emissions over the lifetime of a building and provide substantial savings in energy bills. Such facades can contribute to the further reduction in greenhouse gas emissions in a broad range of contexts in the built environment and other areas of technology and design. The flexibility and adaptability of biomimetic facades exemplify how biological strategies and characteristics can augment and improve performance in different environments, since the organisms that inspire innovation are already well-adapted to the conditions on earth. This study also exemplified a method by which other biomimetic building envelope features may be assessed. Further work is suggested to assess economic viability and constructability of the proposed facades.

“…Negendahl and Nielsen 37 have recommended the use of building performance simulation (BPS) tools in the early design stages and found it beneficial for building performance such as energy, daylight and thermal indoor environment. Correspondingly, Yigit and Ozorhon 38 have emphasized that since the design decisions affecting the energy performance of the buildings are made in the preliminary design phase of the buildings; therefore, the implementation of simulation-based software at the preliminary design stage of the building is of great help to designers.…”

Energy consumption in buildings can be reduced by employing passive design strategies and with the use of alternative energy resources mainly solar photovoltaic and solar thermal. These measures not only help in reducing the energy bills but also help in mitigating climate change efforts. An optimal solution was obtained by the employment of these measures along with the use of building optimization techniques. Heating, ventilating and air conditioning applications are the conventional means for provision of thermal comfort and are also the highest consumers in building energy. The study establishes that certain passive measures in the design features of the building envelope, either during planning and construction or in retrofitting, can help reduce the overall energy consumption of the building without compromising the occupants’ comfort level. This study demonstrated that solar energies as well as the building parameters such as roof/wall thickness, window/wall ratio and optimum sizing of windows can reduce the energy consumption by as much as 33%. The results reflect that the selection of appropriate building parameters is very important in achieving building energy efficiency. MATLAB has been employed along with TOPSIS for optimization to approach a near zero energy building.

Yigit and Ozorhon [13], proposed a methodology to aid designers in satisfying the requirements of government regulations and green building certification programs, while optimizing the energy consumption and maintaining the thermal comfort. Pushkar [14], studied the similarities and differences in performances of LEED 2009 Commercial Interiors and LEED 2009 Core and Shell Development Gold certified projects in Turkey, Spain, and Italy.…”

For the last decade, green buildings have created a new industry of ecological buildings. However, this industry is still newly developing and finds limited implementation opportunities when compared with the traditional building industry. Therefore, for a more preferable green building industry, strategic factors that can have significant effects on the industry should be comprehended. Based on this argument, the present study aims (i) to identify these factors, (ii) to determine their importance levels, and lastly (iii) to find out their current levels of impact on the industry. To this aim, a questionnaire survey was conducted for the Turkish green building industry through 32 industrial practitioners who have an official LEED Credentials. Results obtained were evaluated via the relative importance index method. Consequently, a total of 30 strategic factors were identified. Out of them, 28 were found to be significant while only 16 currently have a significant impact on the industry.
